NEW AND RARE HEPATICS AND MOSSES 

 FROM YORKSHIRE AND DURHAM. 



W. INGHAM. B.A., 

 York. 



During the meeting- of the Yorkshire Naturalists' Union at 

 Buckden, in Upper Wharfedale, from 30th July to 3rd August 

 1904, I found an important variety of a common and well- 

 known hepatic in two distinct localities, one on Buckden Pike, 

 in Mce-county 62, and one on the moor above Deepdale, in 

 Mce-county 64. 



It occurred in large pure patches, distinguished in situ by its 

 peculiar blue-green, or verdigris-green colour. 



In both places the habitat was wet peat, and on the Deepdale 

 Moor the hepatic was partly immersed.
